Abstract (en)
[origin: EP1466665A1] A photocatalyst layer (TiO2 is formed on the surface of a substrate (glass plate) through the intermediary of a monoclinic undercoat layer (ZrO2), and no dead layer is substantially present between the photocatalyst layer and the undercoat layer. Also, by providing a peel preventing layer between the substrate and the undercoat layer, it is possible to eliminate film peeling between the photocatalyst layer and the substrate, defects and discoloration. In the above-described TiO2 layer, metal such as tin (Sn), zinc (Zn), molybdenum (Mo) or iron (Fe) is doped. The phrase "no dead layer is substantially present" means that the thickness of the dead layer is 20 nm or less. The thickness of the photocatalyst layer is preferably from 1 nm to 1,000 nm, more preferably from 1 nm to 500 nm. <IMAGE>
